Harvesters
Harvesters are a unique mechanic of MCLabs. They're meant to replace the need for pistons and/or observers in auto-farm builds within the bounds of the Underworld. They do not work in the Overworld. They are obtainable with the in-game /shop command under Base Building. Each chem will need it's respective harvester (ie: Chorufrium, Pumpkonium, Melonium, Canium, Globerrium). A harvester will harvest all crops in front of it. The harvester must be facing the crops, and on the same Y-level. They will harvest crops for 128 blocks (8 chunks). Type /harvester in-game.
